But Taiwanese iOS developer Hiraku Wang pursued that
discovery even further, suggesting that the new iPad could have a
2,732 x 2,048 screen resolution.

This would ensure that the larger iPad stays at a Retina display.
Since the screen is larger, Apple would have to pack more pixels
per inch to make sure it meets the standard for a Retina display.
The current iPad Air 2's screen measures 9.7 inches and features
a resolution of 2048 x 1536. That means there are 264 pixels per
inch. To keep that same pixel density on a 12.9-inch screen,
Apple would have to increase the resolution to 2,732 x
2,048.

The new finding correlates with research firm
DisplaySearch's predictions regarding the larger iPad's
screen resolution, as
MacRumors pointed out. Back in 2014, the firm predicted that
the 12.9-inch iPad would have a 2,732 x 2,048 resolution display.
We won't know for sure until Apple officially unveils its next
iPad, but other rumors suggest it may come with a Force Touch
screen just like the new MacBook and Apple Watch, and a USB Type
C Port.

Apple typically unveils its new iPads in October, about one month
after it usually announces its new iPhones in September.
